WARIING APPARATUS.

Application filed February 27,1925.

Application `Serial No. 190,501,1iled September 10, 1917, by ,Howard D. Colman, (new Patent No. 1,544,055) discloses a warping lapparatus; comprising a warper .1 5 anda Creel, the latter being adapted tofsup port L- 'so-called cheeses, and being provided with: brakes to stop gjthe 1 rotatien 'Offflle eheesestupon :breakage or excessive Slackening of; the yarn; the beam brake;ofthe-.Warp- 10 enbeing-simultaneously applied toistopzthe beam. .Mechanism is provided vvhiohaets automatically immediately after stoppage of the warping apparatuslto release the beam brake and place the cheese :brakes @in fsueh 5 position that they merely exerta light pressureaipon thejeheeses to prevent coasting thereof-While ,the Warper is being operated at lovv speed, or` Vincase the threads be Casin ally disturbed (thisi lightpressure `,ofthe cheese brakes beinghereinafter termed the drag pressure) and subsequently `to `remove the drag pressure andthus complete the resetting ofl the .blake mechanism.

Themeehanism shownin said: Colman patent for resettingthe. `brakes is' driven by means of a. belt shiftable ontoand off from a; tight pulley.

vThe objeetofthepresent invention is to y provide improved means for driving said 1W resetting mechanismuand for throwing it into and out of operation.

clutch is manually Vthrown in by means `of the bell crank 119 and subsequently auto` matically thrown out by the spring 102.

lVhen it is desired to stop the warper, the trip mechanism may be 'manually operated to release the shaft 73 to the action of the brake-applying springs 'Tl by pulling the before-inentioned hand lever, said lever operating through alink 125 (Fig. 1) as eX- plained in said Peterson 8: Cummings patent. I have described the method of restarting the warper after a stoppage due to a broken or slack thread. Then the warper is stopped for removal of a full beam and for replenishment of tlie creel, the mode of operation preparatory to restart-ing is somewhat different, as will now be explained. c

When the warper stops through the action of the warp'er clock (not shown), the'be'am brake is released and the creel brake mechanism moved to the drag position, as previ ously described. The operative then discern nects Vthe clutch on the rwai-per `as described in Peterson application Serial No. 706,834 filed April 16, 1924. She then pulls the before-mentioned hand lever, thus causing the resetting mechanism to remove the drag pressure from the cheeses and return to high speed operating position. The warper how-v to operate at slow speed, and as soon as thethreads are under tension the operative pulls the herein before-mentioned hand lever, thus (through the action of thelink 125) releas ing the shaft- 7 3 to the action of the spring means 74, whereby the beam brake and the creel brakes are applied. Immediately thereafter the operative pushes the hand lever and thus exerts pressure through the link 118 upon the bell crank 119 to force the bell crank 119 against the stop 126, as shown in Fig. 7, thereby straightening the

toggle

119a and 120 slightly past dead center. The clutch is thus thrown out and locked out of action, the throwing out occurring before the resetting cam has turned more than a negligible' distance. By reference to Fig. T', it will be understood that the locking put of the clutch causes compression of the spring 991. The apparatus is now at rest, with the beam brake and creel brakes set. The threads may now .be severed, and the beam removed.

lf when the warper is running it isnecessary or desirable to stop the warper and leave the brakes on the cheeses, the operative pulls the before-mentioned hand lever and thus releases the brakeapplying springs il to action, 'thereby promptly stoppingvthe warper. sfsoo'n as the warperhasstopped, the operative pushes onthc handl leverv and thereby tlirows'out the clutch Iand locksit out of action, thus preventing thebrakeresetting mechanism from releasing-the benin brake and the cre'el brakes.
